6/7 .r = 3/4 write it as a fraction or as a whole or a mixed number
The solution for "r" is 21/24, which can be simplified to 7/8. The answer can be written as a fraction of 7/8.
To solve for "r" in the given equation, we can use algebraic manipulation.
First, we can multiply both sides of the equation by the reciprocal of 6/7, which is:
7/6: 6/7 · r = 3/4
7/6 · 6/7 · r = 7/6 · 3/4
r = 21/24.
Thus, the solution for "r" is 21/24, which can be simplified to 7/8.
Therefore, the answer can be written as a fraction of 7/8.

Select the graph for the solution of the open sentence. Click until the correct graph appears. |x| + 3 > 3
The correct graph of the inequality ( |x| + 3 > 3) is attached accordingly.
Here is how the above was solvedRecall that the absolute value (or modulus) of a real number x is its non-negative value regardless of its sign. For example, 5 has an absolute value of 5, and 5 has an absolute value of 5.
A number's absolute value can be conceived of as its distance from zero along the real number line.
So, given |x| + 3 > 3
Add minus three to both sides
|x| + 3 + (-3) > 3 + (-3)
|x| > 0
Thus, the absolute value of x is
x > 0 or x < -0
put in the form of inequality, we have

bank wishing to increase its customer base advertises that it has the fastest service and that virtually all of its customers are served in less than 9 minutes. A management scientist has studied the service times and concluded that service times are exponentially distributed with a mean of 6 minutes. Determine what the bank means when it claims 'virtually all' its customers are served in under 9 minutes. Proportion of customers served in under 9 minutes
Answer:
"0.7769" is the right approach. A further explanation is given below.
Step-by-step explanation:
According to the question,
The parameter for the exponential distribution,
μ = 6
x = 9
Now,
⇒ \(P(X < 9) = 1 - exp ( \frac{-x}{\mu} )\)
On substituting the given values in the above equation, we get
⇒ \(= 1 - exp (\frac{-9}{6} )\)
⇒ \(=1-exp(-1.5)\)
⇒ \(=1-0.2231\)
⇒ \(=0.7769\)

This graph shows a proportional relationship.
What is the constant of proportionality?
Enter your answer as a decimal in the box.
Answer:
13.8
Step-by-step explanation:
When y varies directly with x, we have the relationship \(y=kx\) where \(k\) is the constant of proportionality.
To determine \(k\), we simply need to determine the slope, or rate of change, using the coordinate points \((x_1,y_1)\rightarrow(2,27.60)\) and \((x_2,y_2)\rightarrow(6,82.80)\):
\(k=\frac{y_2-y_1}{x_2-x_1}=\frac{82.80-27.60}{6-2}=\frac{55.20}{4}=13.8\)
Therefore, the constant of proportionality is 13.8

The graph of f(x) = (0.5% is replaced by the graph of g(x) = (0.5)* - k. If g(x) is obtained by shifting f(x) down by 5 units, then what is the value of k?
A. K= 1/5
B. k=5
C. k=-1/5
D. k= -5
Answer:
b is the answer
Step-by-step explanation:
the graph of f(x)=0.5x is replaced by the graph of g(x) = 0.5x-k
if g(x) is obtained by shifting f(x) down by 5 units,
then the graph of f(x) = 0.5x is replaced by the graph of g(x) = 0.5x-5

A Ferris wheel at a carnival has a diameter of 72 feet. Suppose a passenger is traveling at 5 miles per hour. (A useful fact: =1mi5280ft.)
(a) Find the angular speed of the wheel in radians per minute.
(b) Find the number of revolutions the wheel makes per hour. (Assume the wheel does not stop.)
a) The Ferris wheel has an angular speed is 12.222 radians per minute.
b) The Ferris wheel makes 116.712 revolutions in an hour.
How to understand and analyze the kinematics of a Ferris wheel
Kinematics is a branch of mechanical physics that studies the motion of objects without considering its causes. In other words, kinematics studies displacements, velocities and accelerations in translation, rotation and combined motion. In this case we find a Ferris wheel rotating around its axis at constant rate.
a) Then, the angular speed (ω), in radians per minute, is determined by the following product:
ω = v / R
Where:
v - Linear velocity at the rim of the Ferris wheel, in feet per second.R - Radius of the Ferris wheel, in feet.Please notice that the length of the radius is the half of the length of the diameter.
If we know that v = 5 mi / h and R = 36 feet, then the angular speed of the wheel is:
ω = [(5 mi / h) · (1 h / 60 min) · (5280 ft / 1 mi)] / [(0.5) · (72 ft)]
ω = 12.222 rad / min
The angular speed is 12.222 radians per minute.
b) A revolution is equal to an angular displacement of 2π radians and an hour is equal to 60 minutes. Then, we can derive the number of revolutions in an hour by dimensional analysis:
n = (12.222 rad / min) · (1 rev / 2π rad) · (60 min / h)
n = 116.712 rev / h
There are 116.712 revolutions in an hour.

Suppose Juan invests in an annuity that pays 6% annual interest, compounded annually. He contributes $4,000 annually for 5 years. What is the value of the annuity after 5 years? Input your answer rounded to the nearest hundred dollars and omit the dollar sign and comma (For example, $42,570.21 should be entered as 42600.)
The value of the annuity after five years is $22,500
The formula for determining the future value of an annuity : A x annuity factor
Annuity factor = {[(1+r)^n] - 1} / r
Where:
A = amount = $4,000
r = interest rate = 6%
n = time = 5
Annuity factor = [(1 + 0.06)^5 -1] / 0.06 = 5.637093
Future value = 5.637093 x $4000 = $22,548.37

Since you found the LCM, multiply the numerators by the number you multiplied the denominators by.
\(\frac{5 *3}{6*3}= \frac{15}{18}\)

Answer:
x = 49
Step-by-step explanation:
The sum of angles is 360
(x + 84) + 80 + 3x = 360
x + 3x = 360 - 84 - 80
4x = 196
x = 196/4 = 49
What is the equation of the line that passes through the point (-5,2)and has undefined slope
Step-by-step explanation:
a line with undefined slope is a vertical line, because x does not change on this line at all, and therefore the shoe is y/0.
a vertical line is parallel to the y-axis.
and to go through the given point, it has to use the x- coordinate.
so, the equation is
x = -5
that's really it.
this is the line of all points with the x-coordinate = -5. any value for y is valid.
The original selling price of an antique clock was c, dollars.
The selling price at a later date was represented by the expression 1.2(0.85c).
Which description could explain what happened to the price of the antique clock?
Therefore, we can conclude that the price of the antique clock increased by 2% from its original selling price.
What is expression?In mathematics, an expression is a combination of numbers, variables, and operations that represents a value or a set of values. Expressions can be simple, such as a single number or variable, or complex, such as a combination of variables and operations.
Here,
The expression 1.2(0.85c) represents the selling price of the antique clock at a later date, which is obtained by multiplying the original selling price c by 0.85 and then multiplying the result by 1.2.
To understand what happened to the price of the antique clock, we can simplify the expression as follows:
1.2(0.85c) = 1.02c
So the selling price at a later date is 1.02 times the original selling price c. This means that the price of the antique clock increased by 2% (since 1.02 is 102% of 1).
